Application filed May 11, R822. Serial; No. 560,267.

To @JZ 167mm, 'it may concern.'

Be it known that I, VVILmAu OBmEN, a citizen of the United States, and a resident of lVashington, in the county of lashington and State of Pennsylvania, have invented certainnew and :useful Improvements in a Combined Belt 'llightener and Brake for Sand Reels; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make anduse the same..

My invention relates to sand-reels and operating mechanism therefor, and has for its object to provide a sand-reel whichis capable of being operated by means of a belt driven by a belt-wheel which is secured on the side of the main belt-wheel.

The invention consists of certain novel features and details of construction as will be more fully described hereinafter, and

lin-ally pointed out in the claim.

I will now describe my invention reference being had to the accompanying `drawings, in which similar letters of reference indicate corresponding parts in the several figures and in which Figure 1, is a side elevation of my invention. Fig. 2, is aiplan view of the same. Fig. 3, 1s a rear elevation,

more clearly sho-wing the arrangement of the parts. Fig. 4:, is a side elevation of the belttightener and operating arms and lever. Fig. 5, is a plan view of one of the arms for holding the tension wheel, and Fig. 6, 1s an edge view of the same. v

ln the drawings A, represents the cross members to which are secured the sillsB, of the belt house. Secured to these cross members A, are the ack-posts C, and sand-` reel posts D. each of which are provided with journal boxes E, vand F, whichy carry the crank-shaft Gr, and sand-reel shaft H.

Intermediate sills I, are secured to the cross members A, and are provided with journal-boxes J, into which is journaled an auxiliary shaft K, the purpose of which will appear hereinafter.

Secured on the crank-shaft G, is the main belt-wheel L, on one side of which is bolted or otherwise secured to the bull-rope-wheel M, and on the opposite or face side the beltwheel N, for operating the sand-reel proper. Secured to the sand-reel shaft I-I, is the sand-reel O` belt-wheel P, brakewheel Q, and arms R, which carry the tension wheel S, and secured on the auxiliary shaft K, are tlreoperating arms vT, and the brake-band U. Thearmsllt and T, being y'connected by means of rods or bars V, which are provided with seriesof holes lV, whichv form means of adyustment between said arms lt and T.

An additional arm X, is secured to the auxiliary shaft K. yThis arm 1s connectedv to one end of the operating rod or bar Y, which runs from the derrick. v

The operation of my invention is as follows:

A belt .Z is placed on and over thebelt` wheel N, passing under the tension wheel S, and over and around the belt-wheel l). The tension-wheel being in the position shown in fulllines Figs. l and 4. ,In this position the brake band U, is `brought into Contact with the brake-wheel Q, which holds the sand-reel O, and shaft H, from revolving.

lWhen-readyfor the bailing process the lever in the derrick (not shown) *is ypulled back which draws the rod' or bar Y, inward towards the derriclr, which movement causes the auxiliary shaft K, to partly revolve, thus drawing the arms T, downward which in turn causes the rods or bars V, andarms R, to descend bringing the tension-wheel S, in contact with the belt Z,'pressing it downwards as shown in Figs. 1, and 4, (dotted lines) and causing it to tighten said belty which will'then be vrevolved by the heltwheel N, said belt in turn will impart a rotary motion to the belt-wheel l?, shaft H, and sand-reel O. When in this position, the

ln'ake-'band U, will be released, thus permitting the sand-reel proper to revolve freely.

When the bottom of the bailer has reached the floor of the derrick, the' lever is pushed back which causes the tension-wheel to be lifted upward slackingthe belt and tightening the brake-band on the brakewheel, preventing the reel proper from turning.

By the use of my improvement the sandreel may be set square with the derrick, whereas by the oldv fashioned wooden sandreel, it hadto be set angling to the derrick and was operated by a friction wheel which was brought into Contact with the main beltwheel on the crank-shaft.

Having described my invention what I claim as new and desire to secure by Letters Patent is: i

A combined belt-tightener and brake for sand-reels, Consisting in combination with a drum-shaft, drum and belt-wheel, of arms movably secured on said drum-shaft and having secured in the outer ends thereof a friction-Wheel, an auxiliary-shaft mounted in bearings which are ksecured to the auxiliary-silis, arms rigidly secured to said auxiliary-shaft sindl connected by means of rods to the outer ends of the arms Vwhich carry the friction-Wheel for moving said friction- Wheei into and out of engagement With the belt, a brake-Wheel secured `on said drumvshaft together With e brake-band one end of which is connected with the auxiliaryshaft and adapted to be drawn into engagement with the brake-Wheel when the tension wheel is released, all substantially as shown and described.

In testimony thatI claim the foregoing as my own invention,v Iha-ve hereunto set my hand in the presence of two Witnesses.
